The R2590 system analyzer sets a new standard for
value in two-way communications testing. The unit’s
light weight (28 lbs.), small footprint (7” x 13.5” x
12”) and optional battery with two hours of run time
combine to make it as valuable in the field as on the
bench.
Here are just a few of the features that are standard
on every R2590:
• 1GHz RF Signal Generator with AM/FM/PM
modulation, 1Hz resolution, and output range from
–10dBm to –125dBm
• Duplex Generator with a fully adjustable
(0 Hz to 1GHz) frequency offset
• 1GHz RF Receiver with 2µV sensitivity and 1Hz
resolution, frequency error meter with actual frequency display, and AM/FM demodulation meters
• Broadband and Selective Power Meters
• 1GHz Spectrum Analyzer with powerful
analytical tools usually found only in expensive
stand-alone instruments
• 50kHz Oscilloscope with voltage and frequency
measurements
• Audio Modulation Synthesizer, including:
Dual tone generator, sub-audible tone generator,
DTMF generator, and external modulation input
• Signal Strength Indicator
• SINAD Meter with AUTO Mode
• CTCSS, DCS, and DTMF Decoder
• 6.4” color LCD Display with external VGA output
• RS232 Port for computer control and “flash”
software updates
Additional optional features include:
– CLEARCHANNEL
™
LTR
– Paging encoder: 2 tone, 5/6 tone, programmable
sequence, POCSAG
– Tracking Generator
– Cable Fault/Antenna Analyzer with Return
Loss Bridge
– Internal battery with up to 2 hours of run time
Powerful, portable, and priced to fit within your budget,
the R2590 is the new standard for two-way communications service monitors.
Big solutions on a small budget.

Standard System Features
Feature Description Benefits
Tracking Generator (option)
View the performance characteristics of many
RF devices with this convenient tracking
generator. A sweep range from 5 KHz to 1 GHz,
with a resolution of 1 Hz, permits accurate
device alignment.
Allows the operator to quickly and easily
diagnose critical problems with receiver front
ends, IFs, helical filters, cavities, combiners
and duplexers.
Full Featured Spectrum Analyzer
The R2590 comes complete with a powerful,
yet very easy to use spectrum analyzer.
Independent Start, Stop, and Span settings
permit ready adjustment of the displayed
spectrum from a 5 KHz window to a full 1 GHz
span width. A fully adjustable reference level,
and a set of four individual markers allows
for precise measurements of levels and
frequencies.
Stop, Average, Peak Hold functions and
one-button measurements such as Occupied
Bandwidth make for a powerful analyzer that
can handle almost any situation.
Our unique ‘Scanning Spectrum Audio’
function replaces the typical ‘look and listen’
capability by tuning the receiver (and the
recovered audio) to an adjustable marker
frequency, rather than the center frequency of
the spectrum display.
The R2590 comes packed with features
typically found on stand-alone spectrum
analyzers, and much more.
This feature is handy when attempting to
identify a variety of signals without the need
to continually change the center frequency of
the spectrum display.
AM/FM Receiver
With a typical sensitivity of less than 2
microvolts at the antenna port, the R2590 can
be used for the off-the-air monitoring of remote
transmitters. Variable squelch aids in picking
up weak signals, but can be set tighter to
ensure the proper S/N ratio for measurement
accuracy.
This feature reduces service costs by enabling
frequent preventative maintenance checks for
system degradation or interference identification without ever leaving the shop.
AM/FM/PM Generator
The R2590 includes a 250 KHz to 1 GHz
AM/FM/PM signal generator that has an
adjustable output level from –125 dBm to
–10 dBm.
The generator output port is fuse-protected,
assuring against damage by the inadvertent
application of power, therefore saving a trip to
the repair shop.
Selectable metering includes a ‘One Button’
SINAD measurement with adjustable target
setting. The R2590 will automatically determine
the RF level needed to produce a specified
SINAD reading.
This flexible signal generator reduces receiver
test time by displaying all the necessary
control information simultaneously. The wide
range of output levels cover all manner of
troubleshooting situations.
The R2590 simplifies routine measurements
with ‘One Button’ convenience.
Full Band Duplex
Offset Generator
Full output level control from –125 dBm to
–10 dBm over the entire frequency range of
the instrument is available from the duplex
offset generator.
Duplex frequency offsets are also fully
variable, from 0 Hz to 1 GHz in 1 Hz steps.
The duplex generator provides enhanced
capability to service equipment such as
repeaters and full duplex radios.
The 1 Hz frequency offset resolution extends
functionality to cross-band repeaters and
component level receiver and transmitter
troubleshooting.
